This paper presents a Hammir tandem mirror confinement performance analysis based on Realta Fusion’s first-of-a-kind model for axisymmetric magnetic mirror fusion performance. This model uses an integrated end plug simulation model including, heating, equilibrium and transport combined with a new formulation of the plasma operation contours (POPCONs) technique for the tandem mirror central cell. Using this model in concert with machine learning optimization techniques, it is shown that an end plug utilizing high temperature superconducting magnets and modern neutral beams enables a classical tandem mirror pilot plant producing a fusion gain Q > 5. The approach here represents an important advance in tandem mirror design. The high-fidelity end plug model enables calculations of heating and transport in the highly non-Maxwellian end plug to be made more accurately. The detailed end plug modelling performed in this work has highlighted the importance of classical radial transport and neutral beam absorption efficiency on end plug viability. The central cell POPCON technique allows consideration of a wide range of parameters in the relatively simple near-Maxwellian central cell, facilitating the selection of more optimal central cell plasmas. These advances make it possible to find more conservative classical tandem mirror fusion pilot plant operating points with lower temperatures, neutral beam energies and end plug performance requirements than designs in the literature. Despite being more conservative, it is shown that these operating points have sufficient confinement performance to serve as the basis of a viable fusion pilot plant provided that they can be stabilized against magnetohydrodynamic and trapped particle modes.
This chapter explores the archaeology of late antique Egypt, discussing its diverse landscapes, urban centres and cultural transitions. It argues that Egypt’s long history and modern development have shaped archaeological research, with papyrology dominating due to the region’s arid climate preserving written records. To illustrate this the chapter examines papyri, inscriptions, settlements and religious structures. Greek texts dominate as a result of their administrative role, while Coptic gained prominence in the sixth century. Excavations reveal a varied urban landscape, from Alexandria’s intellectual hubs to Nile Valley and desert settlements. Sites like Kom el-Dikka in Alexandria and Karanis in the Fayum offer insights into daily life, while Christian sites illustrate religious shifts. A key argument is that Egypt’s late antique past is difficult to reconstruct due to modern occupation and destruction of later remains. The chapter emphasises the need to study non-elite settlements to build a fuller picture of society. Despite political instability and environmental threats, research in desert oases and urban centres continues to expand knowledge of late antique Egypt. Future efforts should focus on preserving and analysing everyday life remains rather than elite structures, ensuring a more balanced historical perspective.
Chapter 6 discusses the representation of memory in trauma narratives. Accounts of victims of childhood trauma are contrasted with the testimony of Holocaust survivors. I argue that that the distinctive qualities of trauma narratives can also be understood as differences in the culturally constructed landscapes of memory that shapes the distance and effort to remember affectively charged and socially defined events. Landscapes of memory draw from implicit models of memory that influence what can be recalled and warranted as accurate. Trauma narratives involve cultural models and metaphors of personal and historical memory. For them to function as personal and collective history, there must be public places for them to be told, acknowledged, and retold. The political recognition of collective identity and history can help create such a place. Individuals’ stories, in turn, can serve as testimony to ground collective history and call for further moral and political response. Understanding the personal, social, and political meanings of trauma in theory and practice requires tracing the systemic loops that link memory, symptom, and response with a landscape of cultural affordances.
This chapter introduces the vision of contract law adopted in this book, based on two concentric spheres: an inner sphere encompasses an economic realm rooted in values such as freedom and sanctity of contract, reflecting a non-interventionist approach that can accommodate imbalanced transactions and an outer sphere shaped by public policy concerns, which embodies social values such as the protection of relational autonomy and human dignity. The chapter justifies the structure of the book, the choice of legal frameworks examined, as well as the relevance of this study for disability equality and contract legal research.
This chapter highlights the interconnection between economic and social values in the contractual realm, rooted in a perception of people as holder of rights and a broad interpretation of autonomy and human dignity that looks beyond individualistic values. With a focus on grossly asymmetrical contracts, it promotes an understanding of vulnerability in the contractual context based on the circumstances of the transaction, rather than on people’s medical conditions. The chapter reflects on the merits and drawbacks of the UN Convention on the Rights of Persons with Disabilities (UNCRPD) as a potential benchmark for promoting a vision of contract law that responds to both economic and social concerns and recognises the equality of all human beings. The second part considers how English contract law could be brought closer to the equality vision promoted by the UNCRPD, proposing an understanding of the contractual realm based on concentric economic and social spheres, shaped by fluid boundaries, and reflecting on the relevance of contract law as part of a broader set of measures to ensure a fairer society.
This chapter examines the archaeology of identity in Late Antiquity, challenging traditional notions of a homogeneous Roman identity. It explores how individual and collective identities evolved between the fourth and seventh centuries, particularly as the Roman Empire fragmented and new cultural identities emerged. The chapter discusses a range of sources, including material culture, burial practices, inscriptions and architectural remains. It critiques past archaeological approaches that focused on elite identities while overlooking broader social diversity. By analysing artefacts such as clothing accessories, funerary goods and urban structures, it highlights how identity was fluid and shaped by factors such as status, gender and ethnicity. This investigation also integrates theoretical perspectives, including post-colonial critiques of ‘Romanisation’, and applies methodologies like isotope and aDNA analysis to reassess past assumptions. A major argument is that Late Antiquity was not just a transition from ‘Roman’ to ‘non-Roman’ identities but a period of complex renegotiation. While elite Romanitas persisted in some regions, new identities emerged through interactions with barbarian groups, Christianity and shifting power structures. The chapter ultimately calls for a more nuanced archaeological approach that moves beyond static labels, recognising identity as a dynamic and context-dependent phenomenon.
This chapter considers how the paradigm of the imperial judge, discussed in Chapter 3, was challenged by the political unrest and legitimacy crises of the Severan period. It does so through a close analysis of rescripts attributed to the child emperor Severus Alexander. Alexander’s rescripts exhibit two unusual rhetorical tendencies. First, several of them predate Alexander’s reign and are in fact relabeled rescripts of his disgraced predecessor Elagabalus; this relabeling shows that the link between imperial authorship and legitimacy had become more tenuous in the late Severan period. Second, rescripts of Alexander are unusually likely to portray the emperor as following prior imperial precedent and especially those precedents of his Severan forebears. I argue that both maneuvers can be thought of as a response to the problems posed by child rule; while Alexander’s own judgment might not be legitimate, his rescripts paint him as a caretaker for a dynastic legal order that was.
This study examined the capacity of ChatGPT-4 to assess L2 writing in an accurate, specific, and relevant way. Based on 35 argumentative essays written by upper-intermediate L2 writers in higher education, we evaluated ChatGPT-4’s assessment capacity across four L2 writing dimensions: (1) Task Response, (2) Coherence and Cohesion, (3) Lexical Resource, and (4) Grammatical Range and Accuracy. The main findings were (a) ChatGPT-4 was exceptionally accurate in identifying the issues across the four dimensions; (b) ChatGPT-4 demonstrated more variability in feedback specificity, with more specific feedback in Grammatical Range and Accuracy and Lexical Resource, but more general feedback in Task Response and Coherence and Cohesion; and (c) ChatGPT-4’s feedback was highly relevant to the criteria in the Task Response and Coherence and Cohesion dimensions, but it occasionally misclassified errors in the Grammatical Range and Accuracy and Lexical Resource dimensions. Our findings contribute to a better understanding of ChatGPT-4 as an assessment tool, informing future research and practical applications in L2 writing assessment.
The conclusion briefly examines the impact of the Ichigo Offensive on Nationalist military provisioning infrastructures. Although US aid and advice resulted in logistical overhauls for specified divisions, improvements to provisioning and standards of living within the Chinese armies were limited in both scope and degree. Even after Japan’s abrupt surrender, grain retained its political and emotive connotations to remain an effective propaganda trope in the Chinese civil war. To feed its armies and sustain the war against Japan, the Nationalists had systematically extracted resources at civilian expense, a reality which gave the post-1945 CCP significant political leverage. In World War II’s longest-standing theater, food mattered most – to rival governments and regimes, to armies, and to civilians.
This chapter examines the development of illuminated manuscripts in Late Antiquity, focusing on their origins, evolution and cultural significance. It argues that illumination was not merely decorative but played a navigational, didactic and symbolic role, aiding text comprehension while reinforcing religious and political authority. Tracing the transition from papyrus scrolls to the codex, the chapter emphasises how the Christian adoption of the codex format facilitated the rise of manuscript illumination. It documents how the earliest illustrated Christian manuscripts emerged in Egypt, influenced by pagan scroll traditions, magical texts and the Book of the Dead. These manuscripts incorporated symbolic elements such as the ankh cross and interlace designs, which later became defining features of Coptic and Byzantine carpet pages. The study then shifts focus to early biblical illustration, highlighting works such as the Vienna Genesis, Quedlinburg Itala and Rabbula Gospels, which reflect the growing role of visual storytelling in Christian texts. The chapter concludes by emphasising the imperial patronage of illuminated books, noting Constantine’s commissioning of grand scriptural manuscripts and the development of treasure bindings adorned with ivory and gold. Ultimately, the study demonstrates how manuscript illumination evolved as a medium of authority, devotion and intellectual transmission across Late Antiquity and the early medieval world.
This chapter explores the architectural evolution of monastic settlements, tracing their development from their early beginnings in Late Antiquity to their eventual institutionalisation within the Christian Church. It examines the diverse forms of monastic architecture, ranging from isolated hermitic dwellings to large coenobitic monasteries, and the various factors that influenced their design. Providing a broad perspective on monastic life across regions such as Egypt, Palestine, Syria, Sinai, Nubia and Western Europe, the chapter argues that monastic architecture evolved in response to practical, spiritual and defensive needs. It highlights how early anchorites lived in secluded hermitages, often repurposing tombs and quarries, while later monastic communities adopted structured compounds featuring churches, refectories and defensive towers. Regional adaptations also played a key role, with fortified monasteries in Sinai, laurae and coenobia in Palestine, and the impact of pilgrimage shaping settlement patterns. Ultimately, the chapter demonstrates how monasteries functioned as economic centres, pilgrimage hubs and defensive structures. It also underscores how archaeological evidence challenges traditional textual narratives, revealing a more complex and pragmatic monastic lifestyle than literary sources often suggest.
The Scientific Advisory Committee on Nutrition (SACN) provides independent advice on nutrition and related health matters to UK government organisations. In keeping with its commitment to openness and transparency, SACN follows a set ‘Framework’ to ensure a prescribed and consistent approach is taken in all its evidence evaluations. Following an update of the SACN Framework in 2020, which addressed some straightforward issues, the SACN Framework subgroup was established in 2021 to consider more complex matters that were not addressed in the 2020 update. The SACN Framework subgroup considered four main topics for update: (1) the different types of evidence evaluations produced by SACN, (2) interpretation of statistical data, (3) tools for assessment of study quality and (4) tools to assess the certainty of a body of evidence for exposure–outcome relationships. The Framework subgroup agreed clear definitions and processes for the different types of evidence evaluations produced by SACN and agreed that interpretation of P values should be informed by consideration of study size, power and methodological quality. The subgroup recommended use of the AMSTAR 2 tool for quality assessment of evidence from systematic reviews and use of the Grading of recommendations, assessment, development and evaluation approach to assess the certainty of evidence. The updated Framework was published in January 2023. This was followed by publication of a further update in October 2024. As a ‘living’ document, the Framework will be subject to regular review by the Framework subgroup and continue to evolve in line with best practice.
Chapter 3 illustrates the poetics of illness experience by examining clinical conversations during a psychiatric assessment of a patient. Patients’ narratives in clinical contexts are often fragmentary and contradictory, reflecting their ongoing struggle to make sense of inchoate experience and position themselves in ways that elicit care and concern. Metaphors of illness experience open up narrative possibilities, but may be blocked by conflicting agendas or cross-purposes of clinician and patient. In place of an overarching integrative narrative are interruption, miscommunication, and mutual subversion. Focusing on narratives, with close attention to the speakers’ rhetorical aims, can identify situations of tension and misunderstanding, which can be clarified through cognitive and social analysis tracing the models and metaphors used in clinical exchanges to their personal meaning and embodiment and outward into the social world where they function as part of discursive systems that organize institutions and confer power. Close attention to metaphor in lived experience, social interaction, and cultural performance can yield an account of the dynamics of clinical conversations.
Chapter 3 on Attribution Science delves deeper into the science that establishes causal links between climate change, specific sources of emissions, and its impacts. The authors illustrate how these scientific developments are enhancing our ability to pinpoint the causes of climate impacts, an evolution crucial to a range of procedural and substantive issues that may arise in climate litigation. The authors also delve into specific regional impacts and showcase how attribution science has illuminated the ways in which different parts of the world are experiencing and responding to the unique challenges posed by a changing climate. This includes case studies in Africa, the Americas, Europe, the South Pacific, and Asia. The authors conclude by addressing the limitations and challenges in the field of attribution science before explaining how it is nevertheless poised to play an ever-more critical role in our collective response to climate change.
